CHURN.

Specification of Letters Patent.

.. Patented Feb. 22, 1910.

Application filed July 14, 1908. Serial No. 443,477.

which the following is a. specification.

This invention contemplates certain new and useful improvements inchurns of that type embodying a vertically reciprocating dasher, and theobject of the invention is an improved device of this character in whichthe churning mechanism may be readily removed from the churnbody, topermit the inspection of the contents of the latter, or for cleaningpurposes or the like, and in which said mechanism may be readilyadjusted within the churn body, so as'to confine the movements of thedasher to the lower part of the churn body, and thus permit a smallquantity of milk to be readily churned. without the loss of time orpower. And a further object of the invention is an improved churn whichembodies peculiar means for effectually beating and agitating the milkso as to induce the separation ofthe oily globules from the fluid, inthe least possible amount of time and with a minimum exertion of power.

With these and other objects in view that will' more fully appear as thedescription proceeds, the invention consists in certain constructionsand arrangements of the parts that I shall hereinafter fully describe,and then point out the novel features thereof, in the appended claim.

For a full understanding of the invention and the merits thereof, and toacquire a knowledge of the detalls of construction, reference is to behad to the following description and accompanying drawing, in which:

Figure 1 is a perspective view partly broken away, of my improved churn;Fig. 2 is a vertical section thereof; and, Fig. 3 is a detail View of asection, showing the adjustable connection of the clamp with theplunger. I

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing, by the samereference characters.

Referring to the drawing, the numeral 1 designates the churn body whichmay be of desired construction, size or design, and which is arranged torest upon a base 2 that is preferably provided with legs 3. This base isextended at one side, in the present. instance, as shown. and is formedat such extended portion with inner and outer standards 4 and 5 whichextend vertically upwardly from the base, and the outer standard 5 ofwhich extends above the inner standard and has its end horizontallydisposed to form a supporting arm 6 that overhangs the base. above thechurn body. A main or drive shaft 8 is journaled between the inner andouter standards, preferably near the upper end of the former, and isprovided with a crank handle 9, by means of which it may be convenientlyrotated. A gear wheel 10 is rigidly mounted upon the main shaft betweenthe inner and outer standards and meshes wit-h a relatively small pinion11 that is mounted upon a driven shaft 12, the driven shaft beingournaled at one end in the outer standard above the main shaft 8 and atits other end in an arm 13 depending from the supporting arm 6, asshown. The shaft 12 projects beyond the arm 13, and is provided beyondthe same with a cranklt to which a pitman 15 is pivotally connected atone end. To the other end of this pitman is swiveled a clamp 16 thatextends through a longitudinal slot 17 opening through the lower end ofa guide arm 18 which depends from the supporting arm 6 beyond the arm 13and which is.

longer than the latter and terminates .above "and in proximity to thetop of the churn body. The clamp 16 is provided with two jaws 19 and 19which are arranged to clutch a vertically reciprocating plunger 20, thejaw 19 being rigid with the projecting end of the clamp, and the jaw l9being laterally movable and carrying a set screw 21 that is also mountedin the rigid jaw 19 and is arranged to hold the movable jaw in operativerelation to the latter to secure the clamp rigidly in the desiredadjusted position upon the plunger. The upper end of this plunger isarranged to be slidingly mounted between two jaws 7 and 7 formed at theextremity of the arm 6 beyond the guide arm 18, the said jaws beingsubstantially similar to the jaws of the clamp, in that one of the jaws7 is rigid with the arm, while the other jaw is laterally movable and isadapted to be held in closed position by a fiat spring 7 formed with anangular disposed end engaging the rigid jaw, as shown. The plungerslides through a removable top or cap which is preferably provided forclosing the upper end of the churn body, the plunger extendingdownwardly into the churn body and being equipped at its lower end withtwo verticall spaced dashers 22 and 23, theblades of w ich are disposedin sta gered' relation.

11 the practical use of my improved churn, the crank handle 9 is rotatedmanually or otherwise, so as to effect the rotation of the main shaftand transmit the said rotary motion to the second shaft 12 crs, wherebythe blades of one dasher are in alinement with the spaces between therespective blades of the other dasher, also causes zig-zag currents inthe liquid as the dashers pass back and forth therethrough, therebyefiecting the maximum agitation of the milk and causing the rapidformation of the butter.

It will be observed that by connecting the pitman 15 with the plunger 20by means of the clamp 16, it is possible to effect the verticaladjustment of the plunger by regulating the point at which the clamp isrigidl securedthereto, thus renderin it possib e to confine themovements of 51c dashers to the lower portion of the churn body, andpermitting a small quantity of milk to be economically churned.

From the above description, in connection with the accompanying drawing,it will be apparent that I have provided a simple, durable and efficientconstruction of churn in which the churning mechanism may be employedwith churn bodies of any suitable construction and of different sizes,which is very light and may be readily carried from place to place withlittle physical exertion, and which consists of comparatively few partsthat may be easily and cheaply manufactured so as to be placed upon themarket at a price not too great to prevent the general adoption of thechurn.

Attention is particularly directed to the fact that the spaced standards4 and 5 serve primarily to provide bearings for the drive shaft 8, andin addition to this func- 'tion also afford between the lower port-ionsthereof, a compartment which is adapted to receive and support the topof the churn body when the same is detached for cleaning purposes or thelike. A rack is thus formed, in effect, which is quite convenient in useand materially enhances the attractiveness of the churn.

Havin what I c aim is: A churn comprisin a base, standards rigid withthe base an extending vertically at one side thereof and spaced apart toprovide a compartment between their lower portions, the standards beingprovided in proximity to their upper ends with alining bearings, one ofthe standards being extended upwardl beyond the other standard,- ahorizontally is osed supporting arm secured to the GXlLGIN ed portion ofsaid standard and overhanging the base and provided at its extremitywith a vertically disposed guide bearing, a guide arm' depending fromthe supporting arm short of the guide bearing and formed with alongitudinal slot opening through its lower end, a bearing arm dependingfrom the supporting arm intermediate ofthe extended portion of thestandard and the guide arm and shorter thus described the invention,

than the latter, a churn body mounted on the base and open at its upperend, a removable top closing the upper end of the churn body, avertically reciprocating plunger operating within the churn body andprojecting upwardly above the same and slidably mounted in the topthereof and in the guide hearing at the extremityof the supporting arm,a member slidably mounted in the slot in the guide arm and extendinghorizontally therethrough and adjustably fixed at one end to theplunger, a pitman connected at one end to the other end of the member, adriven shaft journaled in the extended portion of the standard and inthe relatively short bearing arm depending from the supporting arm, acrank wheel mounted on the driven shaft intermediate of said relativelyshort hearing arm and the guide arm and connected to the other end ofthe pitman, a-drive shaft journaled in the alinmg'bearings in thestandards, and an operative connection between the drive shaft and thedriven shaft.

In testimon whereof I afiix my signature in presence 0 two witnesses;

GEORGE w. reason 1 8.
